Subject: [PATCH 1/2] remoteproc: qcom_q6v5_mss: Replace ioremap with memremap
Date: Wed,  4 Nov 2020 12:33:41 +0530
Message-ID: <1604473422-29639-1-git-send-email-sibis@codeaurora.org> (raw)

Fix the sparse warnings reported by the kernel test bot by replacing
ioremap calls with memremap.

Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Sibi Sankar <sibis@codeaurora.org>
---

I'll send out the patches to convert ioremap to memremap on other
qc remoteproc drivers once I get a chance to test them.
